Dreaming of pomegranate and blood

I have a question about Istikhara. My sister has been getting wedding proposals, so for the ones my parents felt was legitimate, my mother did istikhara. She had a dream that she was cutting a pomegranate and it was very red, that’s all she remembers. My sister did istikhara for the same prospective groom. In her dream she saw blood. She had a dream in which she was crying so she went to sit on a bed which had white sheets on it but when she touched her nose it had blood on it. Then, she went to the bathroom to wipe her nose and noticed that the entire tissue had filled with blood. Now what does this mean. Both dreams are total opposites of each other and we are very confused now.
